Make sure HID devices can be opened before making them available to the application

Browse Source 
This prevents a number of issues where devices are enumerated but not actually able to be opened, like https://github.com/libsdl-org/SDL/issues/5781.

We currently leave the devices open, allowing us to more easily do controller feature detection, protocol negotiation, detect dropped Bluetooth connections, etc. with the expectation that the application is likely to open the controllers shortly.
